Rack Mounting Instructions
1. Elevated Operating Temperature: If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room temperature.
Therefore, consideration should be given to installing the equipment
in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer.
NOTE
In order to ensure reliable operations, please make sure the
operation temperature of the environment does not exceed the
spec. When mounting a rack
-mounted switch with other
operatin
g units in a cabinet without forced ventilation, it is
recommended that 1U of space is reserved between each
rack
-
mounted switch and/or device. It is the responsibility of the
user to ensure that the equipment is installed, operated
, and
used for its intended function in the manner specified by Moxa.
2. Required Air Flow: Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of the
equipment is not compromised.
3. Mechanical Loading: Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
5. Reliable Grounding: Rack-mounted equipment should be reliably
grounded and should not be removed when the equipment is
energized. We suggest to use a conductor that is 0.75 mm
2
or 18
AWG and the thread diameter should be at least 3.5 mm. Particular
attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
NOTE
The rackmount ears can be
installed on the front or rear of the
PT-G7728/G7828 switch.

ATTENTION
Safety First
!
Be sure to disconnect the power cord before
installing and/or
wiring your Ethernet Switch. Calculate the maximum possible
current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each
wire size. If the current goes above the maximum ratings
, the
wiring could overheat,
which can cause
serious damage to your
equipment.
WARNING
This is a Class 1 laser/LED product. Do not stare directly into the
laser beam.
Connecting the Power Inputs
The PT-G7728/PT-G7828 switches support 4 types of power supply:
• PWR-HV-P48: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300 VDC),
one 48VDC PoE power input for PoE+ ports.
• PWR-LV-P48: one 24/48 VDC (18 to 72 VDC), one 48 VDC PoE power
input for PoE+ ports.
• PWR-HV-NP: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300 VDC).
• PWR-LV-NP: one 24/48 VDC (18 to 72 VDC).
For the PWR-HV-P48, the 110/220 VAC/VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to 12 PoE+ ports (50 to 57 VDC is recommended for IEEE
802.3at devices).
For the PWR-LV-P48 models, the 24/48 VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to 12 PoE+ ports (50 to 57 VDC is recommended for IEEE
802.3at devices).
In order to provide power to 24 PoE+ ports, two power modules should be
used.
For the PWR-HV-NP, the 110/220 VAC/VDC power supplies provide power
to the switch.
For the PWR-LV-NP, the 24/48 VDC power supplies provide power to the
switch.

Wiring Requirements
WARNING
Do not disconnect modules or wires unless power has been
switched off or the area is known to be non
-hazardous. The
device may only be connected to the supply voltage shown on the
type
plate. The device is designed for operation with a Safety
Extra
-Low Voltage (SELV) or an isolated power supply, which
means that they may only be connected to the supply voltage
connections and to the signal contact with a SELV or an isolated
power supply in compliance with IEC 60950-1/EN 60950-1.
Power Terminal Blocks
The connection for power input and PoE external power supply is on the
power modules.
PWR-HV-P48/PWR-HV-NP
STEP 1: Insert the neutral/line (L/N/Ground) AC wires into the terminals.
STEP 2: Insert the terminal block connector into the terminal block
receptor.
PWR-LV-P48/PWR-LV-NP
STEP 1: Insert the negative/positive (-/+) DC wires into the terminals.
STEP 2: Insert the terminal block connector prongs into the terminal
block receptor.
PoE Power Terminal Blocks
STEP 1: Insert the negative/positive DC wires into the -/+ terminals,
respectively.
STEP 2: Insert the terminal block connector prongs into the terminal
block receptor.
NOTE
In order to have higher levels of protection
against surge, it is
suggested to install a surge protector in front of the power input
of the
PoE powered device so that it is suitable for use in IEC
61850 conditions.
NOTE
In order to activate the redundant load sharing mode, install two
power
modules on the PT-
G7728/G7828 Series and ensure they
are both active.
- 7 -
NOTE
The reverse power input connection will not activate the device or
PoE input
. In addition, the PoE will only activate when
the system
power input is installed on the same power unit.
Wiring the Relay Contact
Each power module has one relay output that can provide two types of
relay output. Refer to the table below for detailed information.
The relay contact is used to detect user-configured events. Two wires are
attached to the relay pins with normally close and normally open options.
FAULT:
The relay contact of the 3-pin terminal block connector is used to detect
user-configured events. The module provides normally open and
normally closed circuits depending on what the user chooses. For pin
